WHAT'S FOR SALE. This is a nine-bedroom, seven-bath and two half-bath Georgian revival manor built around 1888. It has a banquet-sized dining room, family room, ballroom, large kitchen and a butler area. The house has 10 fireplaces, a library, music and/or card room and a billiard room. It is on seven acres, making it one of the largest privately owned parcels of land for sale on the North Shore.

HISTORY. The estate was owned by the Bostwick family, a clan connected to the Standard Oil fortune and known for promoting equestrian themes such as polo matches. It has been vacant for five years and needs extensive renovation, says listing agent Michael Stanco. There is a good chance the house will be replaced, he says. "The vast majority of people looking at the property have in mind to build a new home on the seven acres," he says.

WHAT'S FOR SALE. This is a three-bedroom, two-bath renovated cape that dates from 1892. It has an eat-in kitchen, formal dining room, family room, two fireplaces, an office, a porch and a patio. It also has an attic, partial basement and a detached, two-car garage. The home is on two acres and backs against a 28-acre tract of land protected by the Peconic Land Trust.

HISTORY. At one time, the house belonged to the father of the founder of the Southold Historical Society, says Geoffrey Fleming, the organization's director, and it is typical of Capes built in the 1800s. The style became popular in the northeast since Capes were cheaper to build than larger post-and-beam homes, he says. They also could be easily expanded and retained heat well, he says.

WHAT'S FOR SALE. This is a seven-bedroom, 3½-bath Tudor that dates to 1907. It has a reception foyer, eat-in kitchen, formal dining room and butler's pantry, formal living rooms on both the first and third floors, a covered sun porch and a second covered porch-entertainment area, a custom fireplace, an office, partial basement with an outside entrance, brick patio and a detached, two-car garage. The house is on 1.37 acres and has beach rights.

HISTORY. The house was built by area shipbuilders when bad weather kept them from their regular duties, says owner Valerie Randall. Her grandparents bought the house in the 1950s, and she spent much of her childhood there. It has not been remodeled and has retained its turn-of-the-century grandeur. "You could almost put a VW in the fireplace," Randall says.
